Cost-performance driven mixed-signal system partitioning: a case study on SDH/SONET OAN interface

For a complex electronic system, early estimation of what technology should be used is very important. In this paper, an optical network access interface is optimally designed according to cost-performance trade-off analysis. The results of the comparison show that for such a complex, mixed-signal system, single chip is not a cost-effective solution compared with single package which has 6 small chips.
